Multi-Component System for Treating Enclosed Environments

Described herein is a heating system where air is drawn into a system where hot gas is injected into it. The air is then discharged at a regulated temperature into an environment through ductwork to heat environments to elevated temperatures and employing functional modules to further condition the air to humidify, dehumidify, decontaminate with airborne free-radicals, and filtrate in both stationary and portable applications. The system is useful to eradicate pests, disease germs, bacteria, viruses, and mold. The system is also useful in water remediation and comfort heating. The system can be configured to create a parallel path to both heat and dehumidify the airflow blended and discharged at the operator-chosen set-point temperatures.

Rugged foam buoyancy modules and method of manufacture

A buoyancy module comprises a multi-layer outer protective shell that has an exterior surface and an interior surface. A first layer of foam buoyancy material is located adjacent to the interior surface. A second layer of foam buoyancy material that includes macrospheres and syntactic foam is surrounded by the first layer of foam buoyancy material. The multi-layer outer protective shell can include a layer of fiberglass backed by a fibrous plastic liner. In this embodiment, the layer of fiberglass provides the exterior surface of the multi-layer outer protective shell, while the fibrous plastic liner provides the interior surface of the protective shell. The second layer of foam buoyancy material can be a precast material. The precast material can include for example macrospheres and syntactic foam. The first layer of foam buoyancy material is preferably a stronger layer than the second layer of foam buoyancy material. Advantageously, the buoyancy module has a plurality of different layers, wherein the components of greatest strength and density are located on the outside. The multi-component system improves ruggedness of the buoyancy material, and provides increased reinforcement at locations subject to increased bending strengths, and provides a buoyancy module of longer life.
